673567 divided by 21 
Our goal is to divide 673567 by 21.

Let's proceed to step 1:
6 divided by 21 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 21

Moving on to step 2:
67 divided by 21 is 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 63 from 67 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 21

Step 3:
21 goes into 43 2 times with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 32.0
If we subtract 42 from 43, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 21

Advancing to step 4:
The number 21 fits into 15 0 times, leaving a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 320.0
If we take 0 away from 15, we end up with 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 21

Advancing to step 5:
156 divided by 21 is 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 3207.0
Subtracting 147 from 156 leaves us with 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 21

Advancing to step 6:
21 goes into 97 4 times with a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 32074.0
Subtracting 84 from 97 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
The number 21 fits into 130 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 32074.6
Subtract 126 from 130 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
When dividing 40 by 21, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 32074.61
Deduct 21 from 40 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 9:
The number 21 fits into 190 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 32074.619
If we take 189 away from 190, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 10:
When dividing 10 by 21, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 32074.619
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
21 can be fit into 100 4 times, resulting in a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 32074.61904
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
If we divide 160 by 21, we get 7 and a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 32074.619047
If we take 147 away from 160, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 13:
130 divided by 21 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 32074.6190476
If we subtract 126 from 130, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
If we divide 40 by 21, we get 1 and a remainder of 19.
The next digit of our result is 1. 
Result so far: 32074.61904761
Subtracting 21 from 40 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 32074.61904761, with a leftover of 1.9e-08.
